Abstract
An original transport and reading apparatus includes an original transport apparatus having a transport path, a first image reading unit that reads an image of an original facing the original transport apparatus, and a second image reading unit that is arranged inside the original transport apparatus and reads an image of the original. The second image reading unit includes a light source, a turning mirror, a lens, an image sensor, and a rotation support shaft, and is accommodated and held by a unit casing. The rotation support shaft performs support so as to allow rotation of the second image reading unit centered on a rotational fulcrum that is arranged along a reading light path for reading an image at a second reading position. Furthermore, a curved original guide having a guiding surface that is curved is arranged in a position corresponding to the light source.
